The proposed Regulation would establish mandatory requirements for all batteries placed on the EU market (i.e. portable batteries, automotive batteries, electric vehicle batteries and industrial batteries). Those requirements relate to sustainability and safety (including restrictions on the use of hazardous substances, in particular mercury and cadmium; carbon footprint rules; mandatory recycled content targets for cobalt, lead, lithium and nickel; performance and durability parameters; removability and replaceability of portable batteries; safety of stationary battery energy storage systems) as well as to labelling and information. The proposal further includes requirements for the end-of-life management of batteries. It sets for instance new collection targets for waste portable batteries (65 % in 2025 and 70 % in 2030), and establishes requirements to facilitate the repurposing of industrial and electric-vehicle batteries as stationary energy storage batteries. It also defines obligations of economic operators linked to product requirements and due diligence schemes; and foresees the set up of an electronic exchange system for battery information, with the creation of a 'Battery Passport'. The proposal also contains provisions on mandatory green public procurement, on conformity assessment, notification of conformity assessment bodies, market surveillance and economic instruments.
